Question
6) Which of the following can be determined from the DNA fingerprint of an individual?
A DNA fingerprint can reveal
Select one or more:
the individual’s risk of heart disease.
how many siblings (brothers and sisters) are found in the family of the individual whose DNA is sampled.
the individual's blood type.
the individual's gender (male or female).
the individual's biological family relationships (paternity, etc.).
7) About 50,000 years ago a small group of people traveled from Africa to Asia, and became the ancestors of
Select one:
modern day people who are of non-African descent.
Homo erectus.
all humans on Earth.
Neanderthals.
modern day people who are of African descent.
8) When the Ice Age arrived 20,000 years ago some humans survived but became increasingly separated into different groups by the ice causing linguistic and cultural differentiation and genetic variation. Which feature of human genetics probably contributed most to the ability of humans to rapidly adapt to changes in climate?
Select one:
Natural selection had already eliminated the weakest candidates.
The many point mutations in genes that provide a library of mutant proteins to be acted on by natural selection.
The fact that humans have pairs of chromosomes rather than a set of individual chromosomes.
People who were sensitive to the cold and invented clothes were then more resistant to the cold climate.
The human epigenome which provided flexible changes in gene expression in response to environmental signals.
9) Single nucleotide polymorphisms (SNPs) are single base pair mutations that
Select one:
are concentrated in the repeated DNA sequences in the genome.
never alter the coding region gene carrying the point mutation
always alter the coding region gene carrying the point mutation.
do not always damage the function of the encoded gene product.
are always located in the non-translated part of the gene carrying the point mutation.
10 ) SNPs can be used to predict the responses of people to certain drugs, for example, the effectiveness of Albuterol to prevent an asthma attack. In the future, SNP profiles will allow doctors to
Select one:
decrease the dosage of Albuterol needed to treat asthma.
avoid using Albuterol for asthma prevention due to expense.
predict in advance which patients will respond well to Albuterol.
increase the number of free samples of Albuterol that they receive from drug companies.
use Albuterol to treat illnesses other than asthma.
Explanation / Answer
6.
DNA fingerprinting, also known as the DNA typing, is a molecular method used to identify variable elements in an individual from a sample of DNA.
DNA fingerprinting can reveal:
The individual's biological family relationships (paternity, etc.)
The individual’s risk of heart disease
The individual's blood type
The individual's gender (male or female)
DNA fingerprinting cannot reveal the information about number of siblings
